Leo Szilard (1898)

Szilard was a Hungarian-American nuclear physicist who, after immigrating to America from Nazi Germany, was instrumental in the development of nuclear weapons. Working with Enrico Fermi, he developed the first self-sustained nuclear reactor based on uranium fission. He was one of the first to realize that nuclear chain reactions could be used in bombs and, in 1939, helped to establish the Manhattan Project. Later he protested nuclear warfare and decided to study what instead? More...

The article says that the first self-sustaining nuclear chain reaction was achieved on December 2, 1942. It's amazing that they were able to drop the first nuclear bomb in less than three years (August 6, 1945). Making and dropping that weapon was a very complex project that required efforts of scientists, engineers and the military. It was something never done before and yet the project was successful in the first attempt.

It is interesting that Einstain, in his letter to FDR, in 1939, mentioned that it might not be possible to carry nuclear bombs by planes. "However, such bombs might very well prove too heavy for transportation by air."

Dropping nuclear bombs on Japan is a controversial political issue which I don't want to comment here. My comments are related to the ability, of the people involved, to realize that kind of project in such a short time period.
